Tire tread



FIG. 1 is a side perspective view of a tire tread showing my new design, it being understood that the tread pattern is repeated throughout the circumference of the tire tread, the opposite side being the same as that shown;

FIG. 2 is a front elevational view thereof, the opposite side being identical thereto; and,

FIG. 3 is an enlarged fragmentary front elevational view thereof.

The dark stippled shading represents the tread grooves, which have the depth shown at the top and bottom of FIG. 2.

The broken lines defining the shoulder rib, sidewall, inner bead, and the peripheral boundary between the claimed tire tread and the shoulder rib depict environmental subject matter that forms no part of the claimed design. 

CLAIM The ornamental design for a tire tread, as shown and described.
